Job summary

Heron Power Inc. in Scotts Valley, CA is seeking a Hardware Applications Engineer to own application-specific testing of our solid state transformer (SST) across AI data centers, utility-scale BESS, and PV plants.

You will bring up hardware in the lab and pilot sites, and write Python scripts to drive test equipment and power converters. You will work closely with the Systems Integration team to diagnose performance gaps, turn findings into product improvements, and develop repeatable, automated

Qualifications

• 1+ years of hands-on experience in power electronics, energy storage, EV, grid, or a hardware-intensive environment.
• Strong grasp of DC circuit fundamentals: resonances, parasitics, slew rates, inductive spikes; correlate test data with simulations.
• Strong scripting and test-automation skills to drive instruments and power converters; log and analyze data.
• Working knowledge of power conversion and battery systems: inverters, BMS, DC pre-charge, contactors and protection, thermal/cooling loops.
• Comfort with lab instrumentation (oscilloscopes, power analyzers, DAQ systems) and comms protocols (CAN and Modbus TCP).
• Scrappy mindset: you get things done with a hundred hurdles in front of you.

Responsibilities

• Own end-to-end application testing of a novel high C-rate battery pack (SuperBBU) with SST, validating ripple mitigation, backup capability, slew rates, and loss profiles.
• Support SST and utility-scale BESS integration testing at pilot sites, covering EMS-to-SST communication, black start and grid-forming coordination, charge/discharge cycling, and round-trip efficiency.
• Support integration testing of the SST with DAS, SCADA and EMS systems.
• Own first pilot deployments: review field performance, identify feature gaps, and work with SW/FW teams to turn findings into product improvements.
• Write and maintain Python-based test automation to command power converters, sequence tests, log data, and turn manual procedures into repeatable automated loops.
• Safely operate power converters, chillers, contactors, and protection hardware; set up cabling, instrumentation, and data acquisition for high-power test runs.
